Need to check transmission fluid. just has a red cap. no dipstick.

The automatic transmission fluid fill location on a 2008 BMW 650i can vary depending on the specific model and transmission type, but generally it is located under the hood and accessed through a dipstick tube.

To locate the dipstick tube for the automatic transmission fluid, follow these steps:

1. Open the hood of the vehicle and locate the transmission fluid dipstick. The dipstick handle is usually yellow, red, or black and is labeled with "ATF" or "trans."
2. Remove the dipstick from the tube and wipe it clean with a lint-free cloth or paper towel.
3. Reinsert the dipstick all the way back into the tube and then remove it again. The fluid level on the dipstick should indicate the current level of transmission fluid.
4. If the fluid level is low, you will need to add automatic transmission fluid. To add fluid, remove the dipstick and use a funnel to pour the fluid into the dipstick tube. Be sure to use the correct type of transmission fluid specified in your owner's manual.
5. Check the fluid level again with the dipstick to make sure it is at the correct level. Add more fluid as needed.

Note: It is important to follow the recommended procedure for checking and adding transmission fluid to your BMW 650i to avoid overfilling the system, which can cause damage to the transmission. If you are unsure about the location of the dipstick or how to properly add fluid, consult your owner's manual or a qualified mechanic for assistance.

the red cap on top of the transmission..best to take it to a mechanic so you don't over fill...since theres no dip stick to check.

• There is a 8mm or 10mm plug on the back of the transmission (underneath the car) When you pull that plug if fluid comes out then it it full. If not you add fluid until it just barely comes out that hole and then the transmission is full.
• Now you add fluid from the top of the transmission. You have to look way down in the engine bay on top of the transmission for a red or black cap. It may say "do not open" or "open by a technician only." Take and pull that cap off and this is the fill spout for the transmission. It's a fill only, not a check. Add from this spout until it comes out that little plug on the back of the transmission.
• You will hear people call this a "sealed" transmission of "non-serviceable." Now you can tell them rubbish lol.
• To check the condition you can look to see if it is getting black or smells burnt. After 50,000 miles the fluid needs flushed and after 100,000 miles you need to change the filter and gasket for the transmission.

To check the transmission fluid level in your car you have to raise the vehicle up and take out the transmission fluid check plug in the transmission. It is locate just below and forward (Towards the front of the car) of where the right axle goes into the transmission housing. To fill it take the plug out then remove the red cap located on the upper side of the transmission housing. You will need a long funnel to add the fluid. Add fluid until it can be seen dripping out of the check plug under the car. Then replace the cap and reinstall the plug. (There is no dipstick on your car)

The Transmission has a check plug and a fill cap. The check plug is located just under the passenger side axle and has a 11 mm head on it. The fill cap is on top of the transmission just underneath the air cleaner box. the transmission must be ideling in park and be warm to the touch , not hot or cold. Fluid should drip from check plug when full.

This model doesn't have a trans dipstick. To check trans fluid level there is a plug on the right side/passenger side above the transmission pan about 2 to 3 inches.The plug has an 11 or 12 mm head on it. Remove this plug while vehicle is running and at operating temperature if fluid comes out of the where the plug was then the level is adequate. To add transmission fluid there is a red or black plastic cap on top of the transmission on the driver side.You will need a transmission funnel to add to it if fluid is need.

GM went to sealed transmissions. That car doesn't have a transmission dipstick.

There's a fill bolt that needs to be removed from the transmission while the car is on a level surface. If transmission fluid comes out, then you're at the proper level. Otherwise fill until fluid starts to come out. (Similar to what would be done on a manual transmission)

Look at the top of the transmission for a little red cap(like the oil fill cap) this is where you add fluid. If you want to check fluid condition, you need to remove cap and stick something in there and smear the fluid on a piece of paper to see color.

Hope this helps you out

There is no dipstick so you can't check it.When you get an oil change have them check tranny fluid.It's the only solution I've heard.

take it to a shop and have them top it up so you can be sure you have the fluid you need to keep the car going as it should,,,,thats your safest bet

Does the car have a transmission dipstick? Look on the passenger side of the engine compartment towards the firewall to find the dipstick tube. If it has a dipstick there will be a square top on it with a locking mechanism. Run car to normal operating temerature, unlock the dipstick pull it out wipe it off push it back in and pull it back out then look to see if the fluid is between the marks. If not just add fluid through the tube.  If you don't have a dipstick there will be a smaller cap with  red plastic lock on it. You will have to break the red lock to get the cap off. There is a special tool from Mercedes to check the level on these non dipstick units. If you think it is low then add 1 quart and road test for proper operation and shifting.
